BY 7 lip/M United States Patent fiFice HORIZONTAL SLIDING REMOVABLE sAsH AND A DUAL TRACK SILL PLATE THEREFOR Gordon W. Love, Birmingham, and Charles A. Pelizzari,

This invention relates to horizontally sliding window construction as integrated in a sash and frame combination and more particularly. pertains to removable horizontally sliding windows and a spring pressed upper track in combination with a double railed back-flanged slanting sill plate.

The utility and economy of horizontally sliding windows is well established in that they are convenient and expeditions in bedroom, diningroom, and kitchen use in that they provide not only the normal light of a vertical double hung window, but also provide wall space for sinks, stoves, beds, dressers, buffets, etc., in the room. While this type of window is known in the prior art, the sashthereof have not been removable so that the windows can be removed from inside the room and the glass thereof cleaned without the use of ladders on the outside of the building.

With the foregoing in view it is the primary object of the instant invention to provide horizontally sliding removable sash in a frame which is simple and economical to manufacture and to use, and which will not leak either air or water and will not stick or freeze up in use so that the windows can be operated easily sideways or can be easilyremoved.

Another object of the invention is to provide a horizontal channel in the frame above the sash having spring pressed guide tracks for both the inside and the outside sash so that the sash can be lifted upwardly off the bottom rail by displacing the guide track and the sashes lifted into the interior of the building.

An object of the invention is to provide a sill plate having dual rails thereon which sill plate is adapted to overlie a slanting sill with the tops of the dual rails thereon at the same height so that the two sash can travel at the same height relative to each other and be easily integrated in sealing relationship with each other and with the frame.

An object of the invention is to provide a sealing block between the rails at the point of juncture of the sash in the center of the frame so that air and water cannot pass beneath the sash and between the rails from the outside of the building into the interior thereof.

An object of the invention is to provide a spring pressed block in the area between the rails beneath the sealing area of the sash so that the block presses up against the bottom of the sash in sealing relationship and against the rail plate to seal out air and water.

An object of the invention is to provide an extruded aluminum sill plate and dual rail combination so that the device can be assembled easily and so that the sill plate and rails will be integrated in proper relationship.

These and other objects of the invention will become more apparent by reference to the following description of horizontally sliding removable windows, the spring pressed guide tracks, and the extruded aluminum sill plate having the dual rails embodying the invention taken in conjunction with the accompanying drawings, in which:

Patented Nov. 19, 1957 Fig. 1 is front elevational view of the frame, sash, guide tracks and sill plate;

Fig. 2 is a vertical cross-sectional view of Fig. 1 taken on the line 22 thereof;

Fig. 3 is a vertical partial cross-sectional view of Fig. 1 taken on the line 3-3 thereof, showing the inventive sealing block;

Fig. 4 is a horizontal cross-sectional view of Fig. 1 taken on the line 4-4 thereof, showing the inventive integration of the sash, sill plate, guide rails, and sealing block;

Fig. 5 is a view similar to Fig. 3 showing an auxiliary adjustment block underneath the sill plate;

Fig. 6 is a cross-sectional view similar to Fig. 3 showing a rubber or resilient sealing block;

Fig. 7 is a view similar to Fig. 6 showing a spring pressed sealing block disposed between the rails of the sill plate; and

Fig. 8 is a cross-sectional view of Fig. 7 taken on the line 88 thereof.

Referring now to the drawings, wherein like numerals refer to like and corresponding parts throughout the several views, the frame 10, Figs. 1 to 4, comprises jambs 11 and 12, a header 13, an outside filler strip 14, and an outside parting stop 15 overlying the juncture between the filler strip 14 and the wall in which the frame is mounted. At the inside of the frame, filler strip 16 is sidewise positioned against the jamb 13 and is overlaid by the molding 17 at the edge thereof, and by the parting stop 19 at the side thereof. It is to be noted that the members 13, 14, 16, and 19 forms a chamber A and that the spring pressed guide tracks 20 and 21 lie in the chamber A and are comprised of grooved face portions for receiving the tongues of the outside sash 22 and the inside sash 23, respectively. The guide tracks 20 and 21 are mounted in the chamber A by inserting the attaching screws 24 through the cups 25 recessed in the grooved face portions of thetracks 21 and 20 and through the conical springs 26 so that when the sashes 22 and 23 are inserted in the tracks 20 and 21, the springs 26 urge the tracks and the sashes downwardly towards the sill 27.

Mounted on the sill 27 is the sill plate 28 which is preferably of the extruded aluminum having formed integral therewith an outside relatively tall guide rail 23, an inside relatively short guide rail 30, and a flange 31 at the back thereof for the purpose of abutting the inside trim sill 32 of the building structure. The sashes 22 and 23 have a groove formed therein at the bottom thereof to receive the tops of the guide rails 29 and 30 so that the sash can travel sidewise on the guide rails 29 and 30 and in the upper tracks 20 and .21.

Referring to Fig. 4, it is noted that when the sash are in the closed position as illustrated therein, their meeting center edges have projections 33 and 34 thereon disposed towards each other so that when the sash are in the closed position, the portions 33 and 3 4 abut each other thereby sealing the space between the sash. Sealing block 35 is disposed beneath the abutting sealing portions 33 and 34 of the sash between the inner and outer rails 29 and 30 and between the inside and the outside sashes so that air "cannot pass therebetween.

When the sash, frame and sill strip are assembled at a mill, the sash plate 28 is so angulated relative to the guide rails 29 and 30 and to the flange 31 that the slant of the sill is coordinated to the angulation of the sill. However, Fig. 5, in the event of converting an existing structure to use the inventive guide rails and tracks, it has been found that if the existing outside sill 36 inclines more than usual, the sealing plate can be blocked up by the use of shingles or clapboard siding 37 so that the sill plate can be established at the correct angle to hold the rails 29 and 30 and the flange 31 in proper relationship.

Referring now to Figs. 3, 6, 7, and 8, it can be seen that the sealing block 35 of Fig. 3 can be made solid such as of aluminum and that the sealing block 35A of Fig. 6 is made of a resilient material such as synthetic resin or rubber so that the strip can be more readily compressed between the sash and between the rails to effect more complete and satisfactory sealing.

Figs. 7 and 8 show a further modified sealing block disposed between the rails comprising a sash contacting face portion 39 and arm portions 40 and 41 having spring tensioned contacting ends 42 and 43 respectively, and it has been found advisable and preferable to locate the device between upstanding pins or blocks 44 and 45 embedded in the rail plate 28 so as to locate the device longitudinally of the plate and yet allow the device to exert full spring pressure between the sash and the plate to seal the areas therebetween against the passage of air and water.

The dual rail sill plate greatly facilitates the integration of the sash and frame in mill work manufacture and the workman is greatly assisted in integrating the sash and frame resulting in fool-proof manufacture and saving the time and material. Apertures 50 are provided in the outside rail 29 in the area of the inside sash 23 so that water falling between the rails 29 and 30 can drain off therethrough.

After the frame is installed in the building, the sash can be easily removed from the inside of the building by moving the sash away from the jamb 12 and then pressing the sash upwardly so as to compress the springs 26 so that the bottom portion of the sash can be easily moved off the rail 30 and the sash then taken into the interior of the room. The outer sash is then moved away from the jamb 11 into the central area of the frame and pressed upwardly against the spring pressed track 20 and the bottom thereof removed from the guide rail 29 and the sash taken into the interior of the room where both sides of the glass may be cleaned and both sashes reinserted in the frame by reversing the removal process.

Although but a single embodiment of the invention has been shown and described in detail, it is obvious that many changes may be made in the size, shape, detail, and arrangements of the elements of the invention within the scope of the appended claim.
